Abstract

PNEUMATSKI CILINDAR SA ZABRAVLJIVANJEM U KRAJNJEM POLOZAJU, NAROCITO ZA POKRETANJE PREKLOPNIH VENTILA ZA ODVOD DIMNIH GASOVA kod uredjaja za odvod dimnih gasova i toplote, sa zabravljivanjem u dva krajnja polozaja, sa klipom (53) ak-tiviranim sa obe strane, koji se pod dejstvom fluida pod pritis-kom moze pomerati u cilindru sa dve cilindarske komore (63, 65;9a, 9b) i sa klipnom polugom (51; 106), pri cemu se u polozajima zabravljivanja elementi za zabravljivanje izvedeni u vidu kuglica (84, 85) pomocu klipova (43, 75) drze u zlebovima klipne poluge (51; 106), pri cemu se klipna poluga (51; 106), alternativno jednom od dva krajnja polozaja zabravljivanja, moze zabraviti u nekom medjupolozaju, naz nacen time, sto je koaksijalno sa klipnom polugom (51; 106) i u odnosu na istu, do oslanjanja na granicnik (72; 108) na klipnoj poluzi (51; 106) svojom ceonom stranom (73), pomerljivo postavljena pomocna poluga (74; 110) za zabravljivanje, koja ogranicava delimican hod klipne poluge (51; 106) i u polozaju delimicnog hoda pruza se u, van jednog (75) od dva klipa (43; 75) za zabravljivanje postavljen, cilindar (77, 113) za zabravljivanje, u kome je pomerljivo ulezisten pomocni klip (78) za zabravljivanje, koji pomocu svog cauras-tog dela (81) u polozaju delimicnog hoda obuhvata kuglice (82), koje zahvataju u prstenasti zleb (83) u pomocnoj klipnoj poluci (74; 110) i koje su radijalno pomerljive, a oslobadja radijalno prema napolje pomerljive kuglice (82) kada se od istih aksijalno pomeri, i sto je pomocni klip (78) za zabravljivanje kod prekoracenja unapred odredjenog pritiska preko pritiskom upravljenog dvosmernog ventila (95) povezan sa prvom sused-nom cilindarskom komorom (65). - Prijava sadrzi jos 19 zavis-nih zahteva.
